PINPOINT TEST A: THE DAYTIME RUNNING LAMPS (DRL) ARE INOPERATIVE

Normal Operation
The DRL module receives voltage at all times through circuit 932 (GY/WH) and ground through circuit 1205 (BK). When the ignition switch is in the RUN position, the DRL module receives a voltage input from circuit 294 (WH/LB) to indicate the ignition switch position. When the DRL module senses the ignition switch in the RUN position, the DRL module provides a pulse width modulated (PWM) voltage to the headlamps through circuit 13 (RD/BK).

Possible Causes
- Fuse
- Circuit 13 (RD/BK) open
- Circuit 294 (WH/LB) open
- Circuit 932 (GY/WH) open
- Circuit 1205 (BK) open
- DRL module
